Title: Low shear polymer injection system with ratio control  between wells
Inventor: STALDER JOHN L

Abstract: LOW SHEAR POLYMER INJECTION SYSTEM  WITH RATIO CONTROL BETWEEN WELLS                   Abstract of the Disclosure A method for the insertion of shear degradable aqueous polymer solutions in a polymer thickened flood wherein a series of pumps are used in a multi-branch system, while reducing shear degradation while maintaining pressure and rate control within any branch of said multibranch system comprising utilizing hydraulic drivers for the pumps wherein the hydraulic power source for the drivers is con-trolled a) by a pressure sensing loop such that a selected preset pressure will not be exceeded by any branch of the injection system, and b) by a rate proportioning control loop whereby the injection rate in the various branches of the multi-branch system will be maintained in a given pro-portion to one another regardless of rate changes in a designated master branch or in the total injection stream. Polymer shear rates are reduced by using plunger pumps, progressive cavity pumps, diaphram pumps or other low shear pumps for the polymer injection while utilizing throttle valves and hydraulic pumps for the hydraulic oil power system.  An optional manually controlled variable speed drive can minimize the amount of bypassed hydraulic power oil.

Abstract: INVENTION:  IMPROVED ALKYLATION PROCESS          INVENTORS:  R. L. STURTEVANT, A. B. GANCY and B. I. KARSAY                 ABSTRACT An improved process for the alkylation of isoparaffins by olefins in the presence of a sulfuric acid catalyst is dis-closed.  Improvement in the octane rating of the product alkylate is achieved by the periodic fortification of the sulfuric acid catalyst with sulfur trioxide-bearing fortifying agents and the incorporation of a holding time to delay the return of the fortified acid to the alkylation zone.  Fortification is employed less than 6% of the time the catalyst is in contact with the hydrocarbons and a preferred water content of between 1.5% and 2.5% is maintained in the acid.  By maintaining an optimum water content and fortifying less frequently, lower water and organic build-up rates are observed than previously thought possible.  By incorporation of a holding time before the acid is returned to the alkylation reactor, there is essentially complete utilization of the fortifying agent for water removal and no free SO3 is available for harmful side reactions with the hydrocarbon feeds in the reactor.           When the organic impurities dispersed in the recycle acid are more completely removed prior to periodic fortification, a wider range of SO3-bearing agents can be applied than previously thought possible.           This nondestructive, periodic fortification process effects improvement in the octane rating of the product alkylate while simultaneously extending the service life of the sulfuric acid catalyst by allowing use of the acid to a higher final organic content.

Abstract: DISHWASHER VENT CLOSING ARRANGEMENT    ABSTRACT OF THE DISCLOSURE        An arrangement for controlling communication of a dishwasher vent opening to allow escape of the humid air from the interior of the dishwasher cabinet during the drying cycle, while sealing the opening during the wash and rinse cycles, including a vertically aligned series of ribs mounted within the opening.  Each rib is trough-shaped to provide a liquid retention channel and the bottom of each rib is posi-tioned within the next succeeding rib such that upon each channel being filled with water, a water seal of the opening is achieved.  Alternate ends of each rib are open to create a cascade flow draining of the water through the rib series.          The water level is maintained by being continuously replen-ished during the wash and rinse cycles to maintain the water seal.  At the end of the rinse cycle, the water drains from the liquid retention channels to enable venting of the in-terior air through the ribs.
